Terry Funk's first retirement happened sometime in 1983 on an All Japan Pro Wrestling card. It's quite the spectacle and you may have even heard a bit of it as a soundbite. (commentary in Japanese; retirement speech in English).
Less than two years later he was wrestling for Vince McMahon and appeared on the Wrestlemania 2 card the following year.
After several retirements later, he returned to All Japan (along with his brother Dory Jr.) in 2013.
